4-[(3as,4r,6ar,8s,9r,9as,9bs)-8-(acetyloxy)-3,6-dimethylidene-2-oxo-octahydrospiro[azuleno[4,5-b]furan-9,2'-oxiran]-4-yl]-2-methylidene-3-oxobutyl acetate

Description

4-[(3AS,4R,6aR,8S,9R,9aS,9bS)-8-(acetyloxy)-3,6-dimethylidene-2-oxo-decahydro-2H-spiro[azuleno[4,5-b]furan-9,2'-oxirane]-4-yl]-2-methylidene-3-oxobutyl acetate belongs to the class of organic compounds known as guaianolides and derivatives. These are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. Based on a literature review very few articles have been published on 4-[(3aS,4R,6aR,8S,9R,9aS,9bS)-8-(acetyloxy)-3,6-dimethylidene-2-oxo-decahydro-2H-spiro[azuleno[4,5-b]furan-9,2'-oxirane]-4-yl]-2-methylidene-3-oxobutyl acetate.
